::
|
|
|
|
bootmeth list [-a] - list selected bootmeths (-a for all)

Description
|
|
-----------
|
|
|
|
The `bootmeth` command is used to manage bootmeths. It can list them and change
|
|
the order in which they are used.
|
|
|
|
See :doc:`../../develop/bootstd` for more information.
|
|
|
|
|
|
.. _bootmeth_order:
|
|
|
|
bootmeth order
|
|
~~~~~~~~~~~~~~
|
|
|
|
Selects which bootmeths to use and the order in which they are invoked. When
|
|
scanning bootdevs, each bootmeth is tried in turn to see if it can find a valid
|
|
bootflow. You can use this command to adjust the order or even to omit some
|
|
boomeths.
|
|
|
|
The argument is a quoted list of bootmeths to use, by name. If global bootmeths
|
|
are included, they must be at the end, otherwise the scanning mechanism will not
|
|
work correctly.
|
|
|
|
|
|
bootmeth list
|
|
~~~~~~~~~~~~~
|
|
|
|
This lists the selected bootmeths, or all of them, if the `-a` flag is used.
|
|
The format looks like this:
|
|
|
|
===== === ================== =================================
|
|
Order Seq Name Description
|
|
===== === ================== =================================
|
|
0 0 extlinunx Extlinux boot from a block device
|
|
1 1 efi EFI boot from an .efi file
|
|
2 2 pxe PXE boot from a network device
|
|
3 3 sandbox Sandbox boot for testing
|
|
glob 4 efi_mgr EFI bootmgr flow
|
|
===== === ================== =================================
|
|
|
|
The fields are as follows:
|
|
|
|
Order:
|
|
The order in which these bootmeths are invoked for each bootdev. If this
|
|
shows as a hyphen, then the bootmeth is not in the current ordering. If it
|
|
shows as 'glob', then this is a global bootmeth and should be at the end.
|
|
|
|
Seq:
|
|
The sequence number of the bootmeth, i.e. the normal ordering if none is set
|
|
|
|
Name:
|
|
Name of the bootmeth
|
|
|
|
Description:
|
|
A friendly description for the bootmeth
|
|
|
|
|
|
Example
|
|
-------
|
|
|
|
This shows listing bootmeths. All are present and in the normal order::
|
|
|
|
=> bootmeth list
|
|
Order Seq Name Description
|
|
----- --- ------------------ ------------------
|
|
0 0 distro Extlinux boot from a block device
|
|
1 1 efi EFI boot from an .efi file
|
|
2 2 pxe PXE boot from a network device
|
|
3 3 sandbox Sandbox boot for testing
|
|
4 4 efi_mgr EFI bootmgr flow
|
|
----- --- ------------------ ------------------
|
|
(5 bootmeths)
|
|
|
|
Now the order is changed, to include only two of them::
|
|
|
|
=> bootmeth order "sandbox distro"
|
|
=> bootmeth list
|
|
Order Seq Name Description
|
|
----- --- ------------------ ------------------
|
|
0 3 sandbox Sandbox boot for testing
|
|
1 0 distro Extlinux boot from a block device
|
|
----- --- ------------------ ------------------
|
|
(2 bootmeths)
|
|
|
|
The -a flag shows all bootmeths so you can clearly see which ones are used and
|
|
which are not::
|
|
|
|
=> bootmeth list -a
|
|
Order Seq Name Description
|
|
----- --- ------------------ ------------------
|
|
1 0 distro Extlinux boot from a block device
|
|
- 1 efi EFI boot from an .efi file
|
|
- 2 pxe PXE boot from a network device
|
|
0 3 sandbox Sandbox boot for testing
|
|
- 4 efi_mgr EFI bootmgr flow
|
|
----- --- ------------------ ------------------
|
|
(5 bootmeths)
